An inventor has created a terrifying means of using a slingshot to apply a condom - and says it is all in the name of beating sexually transmitted infections.

Joerg Sprave, of The Slingshot Channel, designed the Condom Applicator Slingshot Gun in a light-hearted attempt to win a £65,000 ($100,000) grant from the Bill and Melinda Gates Foundation.

Mr Sprave, from Burgkunstadt, in Germany, created the gadget in response to the foundation’s offer of grants for people who could cut sexually transmitted diseases and unwanted pregnancies by creating the next generation of condoms.

BILL GATES CONDOM CHALLENGE

On behalf of the Grand Challenges in Health programme, Bill and Melinda Gates are offering $100,000 worth of start-up money for an idea which could spawn the next generation of condom technology.

Condoms are seen as vital for preventing unwanted pregnancies and STIs but are often shunned on the basis that they are thought to reduce sexual pleasure.

Therefore, the Gates Foundation is looking for an idea which leads to the creation of condoms that increase pleasure in the hope this will encourage people to use them.

Mr Sprave’s contraption allows the unlucky subject to attach a condom to the barrel of the slingshot gun.

They can then prepare the gun for firing before pulling the trigger at close range and releasing the condom at high speed.

Mr Sprave accepts that the device still needs some work as it causes 'fear' and 'pain'

The Bill and Melinda Gates Foundation, a private foundation that focuses on enhancing healthcare and reducing poverty, is offering $100,000 worth of start-up money for any inventor who can increase the appeal of condom use.

It is hoped that the inventor will manage to design a condom that does not reduce sexual pleasure meaning that people are not tempted to go without them.

Bill and Melinda Gates believe that this is important as a means of reducing the spread of STIs, including HIV.
